Anchoring can be a tool in a lot of persuasive situations (not just car sales and not just price). If you have a great plan, you often want to be the first to present it, as then all others will be compared to it. You don't want to wait until the crowd has anchored on another idea. It depends on the situation, but if you are trying to convince someone to "buy" your idea or car, you want to get something for them to anchor on out there quickly.
